The Centers for Medicare & Medicaid Services wants to expand the  model called Comprehensive Primary Care Plus. But an adjustment in how some providers are reimbursed in it could discourage providers from joining, reports Modern Healthcare.

The agency will gather providers into two groups, with “one receiving CPC Plus payments such as care-management fees, performance-based incentive payments or comprehensive primary-care payments, while the other will not,” reported the publication.Paul Ginsburg, a professor of health policy and management at the University of Southern California,  told Modern Healthcare  that the change would make federal attempts to evaluate CPC Plus stronger, but will lead to less participation.

“And there are questions about whether the randomized version of CPC Plus will still count as an alternative pay model under the Medicare Access and CHIP Reauthorization Act.” the publication reported.

Anders Gilberg, senior vice president of government affairs for the Medical Group Management Association, that would be a huge disincentive to providers.

Still, the struggle to win providers could be less to do with CPC Plus itself, and more with the information overload of alternative pay models in recent years, David Introcaso, AMGA’s senior director of regulatory and public policy, told Modern Healthcare.
